    • A method for detecting a status regarding provision or otherwise of a public switched telephone network (PSTN) service to a voice over Internet protocol (VoIP) apparatus includes the steps of: providing a dummy load circuit and an off-hook detection circuit; entering a PSTN mode; coupling the dummy load circuit to a PSTN to simulate an off-hook status of a telephone set; detecting whether there is a dial tone from the PSTN by the off-hook detection circuit; and determining whether the PSTN service is provided to the VoIP apparatus according to a detection or otherwise of a dial tone from the PSTN. A VoIP apparatus employing the method is also provided.
    • 一种用于检测公共交换电话网络(PSTN)服务到因特网协议语音(VoIP)装置的提供或其它状态的方法包括以下步骤:提供虚拟负载电路和摘机检测电路; 进入PSTN模式; 将虚拟负载电路耦合到PSTN以模拟电话机的摘机状态; 检测摘机检测电路是否存在来自PSTN的拨号音; 以及根据来自PSTN的拨号音的检测或其他方式确定PSTN服务是否被提供给VoIP装置。 还提供了采用该方法的VoIP设备。

    • A network device for forwarding packets includes a plurality of interfaces including at least a source interface and a destination interface and a bridge module. The bridge module includes a receiving sub-module, a parsing sub-module, and a sending sub-module. The receiving sub-module receives a packet via the source interface. The parsing sub-module includes a media access control (MAC) table for saving MAC addresses and identifiers of interfaces corresponding to the MAC addresses, parses the packet to retrieve a destination MAC address of the packet, and queries the MAC table to retrieve an identifier of the destination interface. The sending sub-module receives the packet and the identifier of the destination interface, and sends the packet to the destination interface. The parsing sub-module determines whether the network device has an interface mirroring function, and sends the packet to a mirror interface if the network device has the interface mirroring function.
    • 用于转发分组的网络设备包括至少包括源接口和目的接口以及桥接模块的多个接口。 桥模块包括接收子模块,解析子模块和发送子模块。 接收子模块通过源接口接收数据包。 解析子模块包括用于保存与MAC地址相对应的MAC地址和接口标识符的媒体访问控制(MAC)表,解析分组以检索分组的目的地MAC地址,并且查询MAC表以检索标识符 的目标接口。 发送子模块接收报文和目的接口的标识符,并将报文发送到目的接口。 解析子模块确定网络设备是否具有接口镜像功能,如果网络设备具有接口镜像功能,则将该报文发送给镜像接口。

    • A method for testing a 3D camera is provided. The method includes: making a first camera of the 3D camera align with a first picture of a reference picture, wherein, the reference picture includes a second picture, a central point of the first picture and the second picture respectively has a first label and a second label; obtaining an image captured by a second camera of the 3D camera; identifying the first label, the second label, and a central point of the image; calculating an actual angle difference and an actual distance difference according to coordinates of the first label, the second label, and the central point; determining whether the 3D camera is installed appropriately by comparing the actual distance difference with the reference distance difference and the actual angle difference with the reference angle difference respectively.
    • 提供了一种用于测试3D相机的方法。 该方法包括:使3D摄像机的第一摄像机与参考画面的第一画面对准,其中,参考画面包括第二画面,第一画面和第二画面的中心点分别具有第一标签和 第二个标签 获得由3D相机的第二相机拍摄的图像; 识别图像的第一标签,第二标签和中心点; 根据第一标签,第二标签和中心点的坐标计算实际角度差和实际距离差; 通过将实际距离差与参考距离差和实际角度差与参考角度差分别进行比较来确定3D摄像机是否被适当地安装。
